BACKGROUND

With the improvement of living standards, people are paying more and more attention to bone health. Therefore, studies on bone health detection are indispensable. In these studies, it is often necessary to determine a fracture index, which is a parameter for measuring the likelihood of a bone fracture.
In the related art, a bone strength diagnostic device is usually adopted to determine the bone strength. Then, a medical specialist determines the fracture index in accordance with the bone strength. In particular, the bone strength diagnostic device comprises a sound velocity meter, an index calculator and a bone diagnostor. The index calculator is connected with the sound velocity meter and the bone diagnostor. The sound velocity meter is configured to radiate ultrasonic waves to bones and to measure the propagation velocity of the ultrasonic waves in the bones. The index calculator is configured to calculate the bone mineral density (BMD) in accordance with the propagation velocity of the ultrasonic waves in the bones. The bone diagnostor is configured to determine the bone strength in accordance with the BMD.
In the related art, the fracture index is determined by the medical specialist in accordance with the bone strength, and consequently, is impacted by human factors, which results in a relatively lower accuracy of the determined fracture index.

DETAILED DESCRIPTION

The present disclosure will be described in further detail with reference to the enclosed drawings, to clearly present the principles and advantages of the present disclosure. Apparently, the embodiments described are only some embodiments of the present disclosure, rather than all embodiments of the present disclosure.
Please refer to FIG. 1, which shows a block diagram of a fracture index determination system 00 provided in an embodiment of the present disclosure. Referring to FIG. 1, the fracture index determination system 00 may include: a bone mineral density (BMD) acquisition module 001, a balance degree acquisition module 002 and a processing module 003, wherein the BMD acquisition module 001 and the balance degree acquisition module 002 are connected to the processing module 003 respectively.
The bone mineral density (BMD) acquisition module 001 is configured to acquire a BMD of a human body under test. The balance degree acquisition module 002 is configured to acquire a balance degree of the human body under test. The balance degree is used to characterize the standing stability of the human body. The processing module 003 is configured to determine a fracture index of the human body under test in accordance with the BMD and the balance degree of the human body under test. The fracture index may be configured to indicate the risk of a bone fracture of the human body under test. The higher the fracture index is, the higher the risk of the bone fracture is.
To sum up, in the fracture index determination system provided by the embodiments of the present disclosure, the BMD acquisition module may acquire the BMD of the human body under test. The balance degree acquisition module may acquire the balance degree of the human body under test. The processing module may determine the fracture index of the human body under test in accordance with the BMD and the balance degree of the human body under test. In the embodiments of the present disclosure, as the fracture index is determined through the BMD and the balance degree of the human body under test, the problem of a relatively lower accuracy in determining the fracture index is solved. The accuracy in determining the fracture index is improved.
Optionally, in the embodiments of the present disclosure, the fracture index may be in negative correlation with the BMD and may also be in negative correlation with the balance degree. That is, the lower the BMD is and the lower the balance degree is, the higher the fracture index is, and the higher the fracture probability of the human body under test is.
Optionally, the BMD acquisition module 001 may acquire the BMD of the human body under test based on any of the quantitative ultrasound technology, the one-photon absorption technology, the two-photon absorption technology, the quantitative computed tomography (CT) technology and the dual-energy X-ray absorptiometry technology. Exemplarily, the BMD acquisition module 001 may acquire the BMD of the human body under test based on the dual-energy X-ray absorptiometry technology. For example, the BMD acquisition module 001 may comprise an X-ray source, a detector and a processor. The X-ray source may emit X-rays to a bone of the human body under test. The detector may receive the X-rays penetrating the bone of the human body under test and may send the received amount of rays to the processor. The processor may determine the amount of rays absorbed by the bone of the human body under test in accordance with the amount of rays emitted by the X-ray source and the amount of rays received by the detector and may further determine the BMD in accordance with the received amount of rays.
Optionally, in the embodiments of the present disclosure, the balance degree may comprise at least one of a static balance degree and a motion balance degree. The static balance degree is a balance degree that is measured when the human body under test is in a static state, and for example, may be a balance degree that is measured when feet of the human body under test are in a static state. The motion balance degree is a balance degree that is measured when the human body under test is in a moving state, and for example, may be a balance degree that is measured when the feet of the human body under test are in a moving state.
Referring to FIG. 2, which is a partial schematic structural view of a fracture index determination system 00 provided by an embodiment of the present disclosure, the balance degree acquisition module 002 comprises a bearing unit 0021, a static balance degree acquisition unit (not shown in FIG. 2) and a motion balance degree acquisition module (not shown in FIG. 2). The static balance degree acquisition unit and the motion balance degree acquisition unit are connected to the processing module (not shown in FIG. 2).
The bearing unit 0021 is configured to bear the human body under test. The static balance degree acquisition unit is configured to acquire a static balance degree of the human body under test when the human body under test is in a static state on the bearing unit 0021. The motion balance degree acquisition unit is configured to acquire a motion balance degree of the human body under test when the human body under test is in a moving state on the bearing unit 0021. The bearing unit 0021 may be a bearing board. An angle between a bearing face of the bearing unit 0021 and a horizontal plane may be adjusted. That is, the slope (also called inclination) of the bearing unit 0021 may be adjusted. Exemplarily, a groove is formed in a back side (a side, opposite to the bearing face, of the bearing unit 0021) of the bearing unit 0021. A lifting column is disposed in the groove and fixedly secured to an edge of the back side of the bearing unit 0021. The lifting column may be controlled to ascend and descend so as to enable one end of the bearing unit 0021 to rise and fall. Thus, a certain angle is formed between the bearing face of the bearing unit 0021 and the horizontal plane. Optionally, the lifting column may be a pneumatic full-automatic lifting column.
The static balance degree acquisition unit may perform a static balance test on the human body under test to acquire the static balance degree. As shown in FIG. 2, the static balance degree acquisition unit comprises a pressure sensor 0022 and a processing sub-unit (not shown in FIG. 2). The pressure sensor 0022 is disposed on the bearing unit 0021 and connected to the processing sub-unit (not shown in FIG. 2). For example, the pressure sensor 0022 may be a sensor array and is configured to acquire pressure applied by the human body under test to the bearing unit when the human body under test is in the static state on the bearing unit 0021. The processing sub-unit is configured to determine a variation of the pressure applied by the human body under test to the bearing unit 0021 in accordance with the pressure applied by the human body under test to the bearing unit 0021 within a test period, and to determine the static balance degree of the human body under test in accordance with the variation of the pressure.
Optionally, when the static balance test is required, the test time may be set in the processing sub-unit in advance, and may be a preset time (for example, 5 min). When standing on the bearing unit 0021, the human body under test may apply pressure to the bearing unit 0021. The pressure sensor 0022 may continuously acquire the pressure applied by the human body under test to the bearing unit 0021 and send the acquired pressure to the processing sub-unit. The processing sub-unit may determine variation (for example, a pressure graph) of the pressure applied by the human body under test to the bearing unit 0021 in accordance with the pressure sent by the pressure sensor 0022 within the preset time (for example, 5 min), and may also determine the center of the pressure applied by the human body under test to the bearing unit 0021 in accordance with the variation of the pressure. The center of pressure (COP) may also be called a ground reaction force center. Furthermore, the processing sub-unit may determine the static balance degree of the human body under test in accordance with offset of the center of pressure to center of mass of the human body under test.
Optionally, the static balance degree and the offset may be in negative correlation. That is, the higher the offset is, the lower the static balance degree is, indicating a poorer stability of the human body under test.
In the embodiments of the present disclosure, the static balance test may comprise at least one of a single-foot standing test and a functional reaching test. When the single-foot standing test is required, the human body under test stands on one foot on the bearing unit 0021 and is physically relaxed naturally. The pressure sensor 0022 continuously acquires pressure applied by the human body under test to the bearing unit 0021 and sends the acquired pressure to the processing sub-unit. The processing sub-unit determines the static balance degree of the human body in accordance with the pressure sent by the pressure sensor 0022. When the functional reaching test is required, the human body under test stands on both feet on the bearing unit 0021 and extends arms forwards. The pressure sensor 0022 continuously acquires the pressure applied by the human body under test to the bearing unit 0021 and sends the acquired pressure to the processing sub-unit. The processing sub-unit determines the static balance degree of the human body in accordance with the pressure sent by the pressure sensor 0022.
The motion balance degree acquisition unit may perform a motion balance test on the human body under test to acquire the motion balance degree. As shown in FIG. 2, the motion balance degree acquisition unit comprises a camera 0023 and a processing sub-unit (not shown in FIG. 2). The camera 0023 is disposed in a target position, a preset distance away from the bearing unit 0021, and is connected to the processing sub-unit (not shown in FIG. 2). The camera 0023 is configured to acquire a motion image of the human body under test when the human body under test is in a moving state on the bearing unit 0021, and to send the acquired motion image of the human body under test to the processing sub-unit. The processing sub-unit is configured to determine motion information of the human body under test in accordance with the motion image of the human body under test, and to determine the motion balance degree of the human body under test in accordance with the motion information of the human body under test.
Optionally, when the motion balance test is required, a test period may be set in the processing sub-unit in advance, and may be a preset time (for example, 10 min). When the human body under test moves on the bearing unit 0021, the camera 0023 may continuously acquire the motion image of the human body under test and send the acquired motion image to the processing sub-unit. The processing sub-unit analyzes the motion image sent by the camera 0023 within the preset time (for example, 10 min) to obtain the motion information of the human body under test. The motion information may comprise at least one of step speed, step size and percentage of single-foot support time. A corresponding relationship between the motion information and the motion balance degree may be stored in the processing sub-unit. The corresponding relationship between the motion information and the motion balance degree is inquired in accordance with the motion information obtained through analysis to obtain the motion balance degree of the human body under test.
The corresponding relationship between the motion information and the motion balance degree may be set in the processing sub-unit in advance by a medical specialist and may also be obtained in the way that the processing sub-unit performs balance degree training on sample data in advance. In the embodiments of the present disclosure, the step speed may be the average step speed at which the human body under test moves on the bearing unit 0021. The step size may be the average step size at which the human body under test moves on the bearing unit 0021. The percentage of single-foot support time may be the percentage of single-foot ground contact time to the total motion time when the human body under test moves on the bearing unit 0021.
In the embodiments of the present disclosure, the motion balance test may comprise at least one of a platform motion balance degree test, a slope motion balance degree test and an across-obstacle motion balance degree test. When the platform motion balance degree test is required, as shown in FIG. 2, the bearing face of the bearing unit 0021 is kept parallel to the horizontal plane. The human body under test (not shown in FIG. 2) stands on the bearing unit 0021 and moves (for instance, walks slowly, walks fast and runs). The camera 0023 acquires the motion image of the human body under test and sends the acquired motion image to the processing sub-unit. The processing sub-unit analyzes the motion image sent by the camera 0023 to obtain the motion information of the human body under test, and inquires the corresponding relationship between the motion information and the motion balance degree to obtain the motion balance degree of the human body under test.
When the slope motion balance degree test is required, as shown in FIG. 3, the height of one edge of the bearing unit 0021 is adjusted to form an angle α (the bearing face of the bearing unit 0021 has a certain slope) between the bearing unit 0021 and the horizontal plane. The human body under test (not shown in FIG. 3) stands on the bearing unit 0021 and moves (for instance, walks slowly, walks fast and runs, etc.). The camera 0023 acquires the motion image of the human body under test and sends the acquired motion image to the processing sub-unit. The processing sub-unit analyzes the motion image sent by the camera 0023 to obtain the motion information of the human body under test, and inquires the corresponding relationship between the motion information and the motion balance degree to obtain the motion balance degree of the human body under test.
When the across-obstacle motion balance degree test is required, as shown in FIG. 4, the bearing face of the bearing unit 0021 is kept parallel to the horizontal plane (or, a certain angle is formed between the bearing face of the bearing unit 0021 and the horizontal plane). An obstacle is disposed on the bearing face of the bearing unit 0021. The human body under test (not shown in FIG. 4) stands on the bearing unit 0021 and moves across the obstacle (for instance, walks slowly, walks fast or runs, etc.). The camera 0023 acquires the motion image of the human body under test and sends the acquired motion image to the processing sub-unit. The processing sub-unit analyzes the motion image sent by the camera 0023 to obtain the motion information of the human body under test, and inquires the corresponding relationship between the motion information and the motion balance degree to obtain the motion balance degree of the human body under test.
Furthermore, referring to FIG. 5, which shows a block diagram of another fracture index determination system 00 provided by an embodiment of the present disclosure. Referring to FIG. 5, on the basis of the structure as shown in FIG. 1, the fracture index determination system 00 further comprises a physical sign parameter acquisition module 004 that is connected to a processing module 003.
The physical sign parameter acquisition module 004 is configured to acquire a physical sign parameter of a human body under test and sends the acquired physical sign parameter to the processing module 003. The processing module 003 is configured to determine a fracture index of the human body under test in accordance with a bone mineral density (BMD), a balance degree and the physical sign parameter of the human body under test.
The physical sign parameter may comprise but not limited to at least one of age, height, weight and a health parameter. The health parameter is used to indicate a health condition of the human body under test. The health condition may mean whether the human body under test suffers from a disease and what kind of disease (for instance, hypertension and heart disease, etc.) the human body under test suffers from. Besides, the health parameter may adopt different data to indicate whether the human body under test suffers from a disease and what kind of disease the human body under test suffers from. Optionally, the physical sign parameter may further comprise parameters including body temperature, pulse, breathe, blood pressure and the like. The types of the parameters included by the physical sign parameter will not be limited by the embodiments of the present disclosure.
In the embodiments of the present disclosure, the physical sign parameter acquisition module 004 may be an input module. A user may input the physical sign parameter of the human body under test by means of the input module, so that the physical sign parameter acquisition module 004 may acquire the physical sign parameter. Optionally, the user may input parameters including sex and the like of the human body under test by means of the input module, which will not be limited by the embodiments of the present disclosure.
The processing module 003 may determine the fracture index of the human body under test in accordance with the BMD, the balance degree and the physical sign parameter of the human body under test. Optionally, the processing module 003 may determine the fracture index of the human body under test in accordance with the BMD, the balance degree of the human body under test and a fracture index model. The fracture index model may be built and provided in the processing module 003 in advance. The fracture index model may be built in the way that physical sign parameters, BMDs, balance degrees and fracture indexes of m human bodies are acquired to obtain m groups of data. Each of the m groups of data comprise the physical sign parameter, the BMD, the balance degree and the fracture index and correspond to one human body. The m groups of data are analyzed to obtain the fracture index model. Exemplarily, a linear equation may be built in accordance with each group of data. Thus, m linear equations are obtained and may comprise:
${\begin{matrix} f_{1} = k_{1} \times a_{1} + k_{2} \times h_{1} + k_{3} \times g_{1} + k_{4} \times d_{1} + k_{5} \times b_{1} + k_{6} \times j_{1} + k_{7} \\ f_{2} = k_{1} \times a_{2} + k_{2} \times h_{2} + k_{3} \times g_{2} + k_{4} \times d_{2} + k_{5} \times b_{2} + k_{6} \times j_{2} + k_{7} \\ \dots \\ f_{m} = k_{1} \times a_{m} + k_{2} \times h_{m} + k_{3} \times g_{m} + k_{4} \times d_{m} + k_{5} \times b_{m} + k_{6} \times j_{m} + k_{7} \end{matrix},$
where a₁represents the age of a human body 1 in the m human bodies, h₁represents the height of the human body 1 in the m human bodies, g₁represents the weight of the human body 1 in the m human bodies, d₁represents the BMD of the human body 1 in the m human bodies, b₁represents the balance degree of the human body 1 in the m human bodies, j₁represents the health parameter of the human body 1 in the m human bodies, and f₁represents the fracture index of the human body 1. Similarly, a₂represents the age of a human body 2 in the m human bodies, h₂represents the height of the human body 2 in the m human bodies, g₂represents the weight of the human body 2 in the m human bodies, d₂represents the BMD of the human body 2 in the m human bodies, b₂represents the balance degree of the human body 2 in the m human bodies, j₂represents the health parameter of the human body 2 in the m human bodies, f₂represents the fracture index of the human body 2, and so on. k1, k2, k3, k4, k5 and k6 are sequentially coefficients of age, height, weight, BMD, balance degree and health parameter. k7 is an additional coefficient.
The m linear equations are solved to obtain specific values of k1, k2, k3, k4, k5, k6 and k7. Then, the fracture index model may be obtained in accordance with the values of k1, k2, k3, k4, k5, k6 and k7, and may be: f=k₁×a+k₂×h+k₃×g+k₄×d+k₅×b+k₆×j+k₇, where a, h, g, d, b and j are all unknown numbers and sequentially represent age, height, weight, BMD, balance degree and health parameter. After the fracture index model is built, the processing module may substitute the BMD, the balance degree and the physical sign parameter of the human body under test into the fracture index model. The fracture index of the human body under test is obtained through calculation.
It should be noted that the above-mentioned solution of building the fracture index model is merely exemplary. In the embodiments of the present disclosure, the fracture index model may be built by other means. For example, the fracture index model may be built by a support vector machine (SVM) algorithm, a neural network algorithm or the like. The fracture index model may also be a back propagation (BP) neutral network model.
In the embodiments of the present disclosure, the value range of the fracture index may be [0,10]. 0 indicates no fracture risk of the human body. 10 indicates an extremely high fracture risk of the human body.
Furthermore, continuously referring to FIG. 5, the fracture index determination system 00 may further comprise a motion item determination module 005 that is connected to the motion balance degree acquisition unit (not shown in FIG. 5). The motion item determination module is configured to determine the motion item that corresponds to the human body under test in accordance with the BMD or the physical sign parameter of the human body under test. The motion balance degree acquisition unit is configured to acquire the motion balance degree of the human body under test when the human body under test performs the motion item that corresponds to the human body under test on the bearing unit.
The motion item may comprise motion type and motion intensity. The motion type is test type that may comprise the platform motion balance degree test, the slope motion balance degree test and the across-obstacle motion balance degree test. The motion intensity may comprise primary intensity, secondary intensity, tertiary intensity and the like. The primary intensity indicates a relatively lower motion intensity (for example, slow walking). The secondary intensity indicates an appropriate motion intensity (for example, fast walking). The tertiary intensity indicates a relatively higher motion intensity (for example, running).
Optionally, a BMD threshold may be set in the motion item determination module 005 which may determine the motion item that corresponds to the human body under test in accordance with the relationship between the BMD of the human body under test and the BMD threshold. Optionally, when the BMD of the human body under test is more than or equal to the BMD threshold, it is believed that the human body under test has a relatively higher BMD. At this time, the motion item determination module 005 determines the motion item with the relatively higher motion intensity as the motion item that corresponds to the human body under test. For example, the slope motion balance degree test item with the tertiary motion intensity is determined as the motion item that corresponds to the human body under test. When the BMD of the human body under test is less than the BMD threshold, it is believed that the human body under test has a relatively lower BMD. At this time, the motion item determination module 005 determines the motion item with the relatively lower motion intensity as the motion item that corresponds to the human body under test. For example, the platform motion balance degree test item with the primary motion intensity is determined as the motion item that corresponds to the human body under test.

Exemplarily, when the physical sign parameter is the health parameter, the motion item with the relatively lower motion intensity may be determined as the motion item that corresponds to the human body under test if the health parameter indicates that the human body under test suffers from hypertension or heart disease. For example, the platform motion balance degree test item with the primary motion intensity is determined as the motion item that corresponds to the human body under test.

The processing module 003 may compare the action information sent by the three-dimensional motion capture module 006 with self-stored action information to determine whether there exists a motion action that is identical with the motion action of the human body under test in the motion action indicated by the self-stored action information or not. If yes, the processing module 003 determines the motion action of the human body under test as a correct motion action. If not, the processing module 003 determines the motion action of the human body under test as a false motion action. At this time, the processing module 003 may generate the test guidance information that is configured to indicate the motion action. The motion action indicated by the test guidance information is the motion action that is nearest to the motion action of the human body under test in the motion action indicated by the action information stored in the processing module 003.
